Rolls off (attenuates) the high-frequency
content of the signal above the set frequency.
The LPF is OFF when set to THRU.

Time: 0.3 ... 10 seconds
Sets the amount of time it takes for the reverb
sound to decay to an inaudible level.

Balance: 0% ... 100%
Sets the amount of reverb in relation to dis-
tortion. A setting of "0" produces distortion
only, while a setting of "100" produces dis-
tortion plus maximum reverb. "50" produces
an approximately even balance between the
distortion and reverb sound.
